Firewall configuration API

This API is based on the Device Configuration API framework. For guidance on how to use these APIs, please refer to the Device Configuration APIs section in the VAPIX®.

Overview

The Firewall Configuration API makes it possible to add, fetch, edit, reorder, and remove existing firewall rules. With this API, you can also activate/deactivate the firewall, check if firewall is active, and test the firewall rules before saving.

info

This API includes operations on sensitive data. You must use a secured channel for the communication transmissions.

Use cases

Manage firewall

The Firewall Configuration API can activate or deactivate the firewall, and check if the firewall is activated.

Activate firewall

This example shows how to use firewall.v1.activated to activate the firewall.

JSON request:

PATCH/config/rest/firewall/v1/activatedHTTP/1.1
HOST:my-device
Content-Type:application/json

{
"data":true
}

JSON response:

HTTP/1.1200OK
Content-Type:application/json

{
"status":"success"
}

Check if the firewall is activated

This example shows how to use firewall.v1.activated to check if the firewall is activated.

JSON request:

GET/config/rest/firewall/v1/activatedHTTP/1.1
HOST:my-device
Content-Type:application/json

JSON response:

HTTP/1.1200OK
Content-Type:application/json

{
"status":"success",
"data":"true"
}

Manage firewall rules

You can apply the firewall rules to filter or rate limit inbound traffic to the device.

During a test run, the pendingRules are active and the firewall rules remain in the pendingRules list until they are either confirmed by using confirmRules or cleared by using clearPendingRules.

Custom errors

Error code	Error message	Description
`100`	Invalid IP address.	The IP address is not a valid IPv4 or IPv6 address.
`103`	Invalid request.	The request doesn't meet the internal requirements. See the following use cases.

Edit firewall rules

This example shows how to use firewall.v1.conf.setRules to edit the existing firewall rules.

The changes are written to the activeRules list. If fallbackTime is set to 0, the changes are immediately applied and the current pendingRules is cleared.

info

If you set rules with fallbackTime greater than 0 when the firewall is inactive, error 103 is returned.

For each rule, only one option from layer 2, 3, or 4 is allowed. To apply a rule to multiple options within the same network layer, you must create separate rules.
